http://owaa.org is a WPMU install. A recent upgrade to WP 3.2.1 broke just one of the WPMU sites. The menu bar of http://www.owaa.org/ou looks like this: http://owaa.org/wpmu-menu-bar-problem.jpg. Hovering over the home button presents what looks like a CSS problem, but you can't click on it, either. Yet, you can hover/click on the second menu item just fine.
What troubles me is that this site uses the same theme as all the other WPMU sites, yet it is the only site is having problems with the menu bar.
My hosting service said this, though I don't really know what the error means:
"I investigated a bit further on this to try and provide you with more options to work on getting this resolved. I was able to connect through the WordPress admin and pulled the following PHP error from the log as I visited the homepage. It seems to indicate lingering database errors:
[05-Sep-2011 10:57:52] WordPress database error Incorrect key file for table
'./beta/wp_8_postmeta.MYI'; try to repair it for query SELECT SQL_CALC_FOUND_ROWS
wp_8_posts.* FROM wp_8_posts LEFT JOIN wp_8_postmeta AS miniposts_meta ON
(wp_8_posts.ID = miniposts_meta.post_id AND miniposts_meta.meta_key='_mini_post' AND
miniposts_meta.meta_value=1) WHERE 1=1 AND wp_8_posts.post_type = 'post' AND
(wp_8_posts.post_status = 'publish' OR wp_8_posts.post_status = 'private') AND
(miniposts_meta.meta_key IS NULL OR miniposts_meta.meta_value = 0) ORDER BY
wp_8_posts.post_date DESC LIMIT 0, 10 made by require, wp, WP->main, WP->query_posts,
Troubleshooting I have done so far (with no fix to the problem):
-Deactivated all plugins to see if this resolved problem.
-Tried the TwentyEleven theme.
-Reset the plugins folder by FTP.
-Redo 3.2.1 upgrade (manually)... after first updating all plugins to current versions.
Thanks for your help!
